Hi I got this link for new topic.

pls answer genuine doubt raised during analysis of pipeline.

I am using material A790 UNS 32750 material

SMYS is 551 MPA

Deaerated is 446 MPA as per DNV OS F101

Hence entered Sy cell 446
and Fac 0.72

load case modeled is Ope L1= W+D1+T1+P1

As per Asme 31.8 all stress for ope is S,

ans Se is SMYS*T*Fac


hence in stress summary in output

I should get 446
or

446*.72= 321.12 Mpa


But I got 356 Mpa

How is this possible pls explain at earliest.


Regards,
Suhas
